Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

The figure shows a schematic cross-sectional view of the cuvette. A cylindrical stainless steel tube 1, which is gold-plated inside, has a concentric enlargement 2 at its two ends. Two KBr windows 3 are inserted in enlargements 2 and are axially forced against the center part of tube 1 by bored screw caps 4; tight sealing being achieved by rings 5. The gas to be analyzed is admitted to tube 1 through gas inlet 6 and escapes through gas outlet 7. A stream of purging gas is admitted to one of the enlargements 2 through gas inlet 8, purging the periphery of one KBr window 2 and flowing through gas outlet 9, a thin tube 10 and through gas inlet 11 into the other enlargement 2, where it purges the periphery of the other KBr window 3 to escape through gas outlet 12.

Gas Cuvette for Fourier Transform Infrared Spectrometer

The figure
shows a schematic cross-sectional view of the
cuvette. A cylindrical stainless steel
tube 1, which is gold-plated
inside, has a concentric enlargement 2 at its two ends. Two KBr
windows 3 are inserted in enlargements 2 and are axially forced
against the center part of tube 1 by bored screw caps 4; tight
sealing being achieved by rings 5. The gas to be analyzed is admitted
to tube 1 through gas inlet 6 and escapes through gas outlet 7. A
stream of purging gas is admitted to one of the enlargements 2
through gas inlet 8, purging the periphery of one KBr window 2 and
flowing through gas outlet 9, a thin tube 10 and through gas inlet 11
into the other enlargement 2, where it purges the periphery of the
other KBr window 3 to escape through gas outlet 12.

The cuvette
is suitable for trace analysis of reactive gases in
a Fourier transform infrared spectrometer.
